So, I'm a bit confused here. Are you sugesting that load during
transcoding is the problem, or load during recording? Am I right that
these messages are printed by the transcoder (and not by the
recorder)? If so, it would seem that only what's going on during
recording would matter, and given that I have a device w/ a HW encoder
it would seem that only some sort of PCI problem could cause the data
to get messed up (or it's a problem w/ the capture card or driver).

How does this look:
tivi% lspci | grep Conexant
02:06.0 Multimedia video controller: Conexant CX23880/1/2/3 PCI Video
and Audio Decoder (rev 05)
02:06.2 Multimedia controller: Conexant CX23880/1/2/3 PCI Video and
Audio Decoder [MPEG Port] (rev 05)
tivi% setpci -s 02:06.0 MAX_LAT
tivi% setpci -s 02:06.2 MAX_LAT
